7 Ways Diamond Mining Practices Shape Sustainability Across the Supply Chain

7 Ways Diamond Mining Practices Shape Sustainability Across the Supply Chain

Jewelry Guidebook

How a diamond is found, planned, mined, processed, and tracked determines most of its environmental and social footprint—and shapes whether it meets modern expectations for responsible sourcing. Sustainability in diamond mining focuses on minimizing land and water disturbance and carbon intensity per carat, protecting biodiversity, supporting safe, decent livelihoods, and maintaining traceable, transparent custody from mine to market. In practice, seven levers—resource classification, mining method, processing technology, traceability, ASM integration, environmental management and closure, and market localization—drive results across land, water, carbon, livelihoods, and transparency. Market context is shifting: global natural diamond production fell from more than 175 million carats in 2005–06 to about 121 million in 2023, and by 2025 roughly one‑third of fine jewelry purchases could be influenced by ESG factors, according to McKinsey’s diamond industry analysis. At Jewelry Guidebook, we translate these technical levers into plain‑language guidance for buyers and professionals evaluating sourcing claims.
